Hi!
I'm about to build myself a sort of custom mixer that fulfill all my needs... ;D but I need some advise for the fader implementation.
Here is how I designed the project so far:
It will be based around the 51x format so various types of preamps and eq's can be used in any combination.
I call it The 51x Tracking Rack
There will also be an option to patch e.g. a compressor in from the two slots in the upper right corner (fx1 & fx2) and an external fx insert for each channel.
The routing panel could look something like this:
There is 4 aux outputs so two or more channels can be summed together before they hit the soundcard. I used the following circuit:
https://dl.dropboxusercontent.com/u/14107936/Tracking%20Rack%20tr%C3%A5d/SUM-12_schematic.pdf
The idea is that the signal can either pass the tracking rack without being affected by any IC's and stuff like that or it can be eq'ed, compressed, attenuated and summed together...
But the attenuation is the problem right now.
The whole thing is balanced - between every 500 module and through the entire routing. So I thought I could make a balanced attenuator ala this one:
http://classicapi.com/catalog/product_info.php?cPath=48&products_id=254 but Im someone told me that it fu**s with the signal in a bad way.
And what would be really cool is to have some real faders. But with the option of bypassing them.
The way I see it I need to "debalance?" the signal, attenuate it, and balance it again? Or?
Here is a diagram of the circuit components:
How do I attenuate the signal correctly? can I make a circuit based on the NE5532?
Does anybody have a fader circuit in mind?
Best,
Kasper
